Abstract:Endothelial cell (EC) migration is critical for healing arterial injuries, such as those that occur with angioplasty. Impaired reendothelialization following arterial injury contributes to vessel thrombogenicity, intimal hyperplasia, and restenosis. Oxidized lipid products, including lysophosphatidylcholine (lysoPC) induce TRPC6 externalization leading to increased [Ca2+]i, activation of calpains and alterations of the EC cytoskeletal structure that inhibit migration. The p110α and p110δ catalytic subunit iso… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
